AK hit flop not sure how to aproach the turn

[AFennewald]

This is my first post in this forum. I am a successful NL tourney player trying to learn cash games. I'm not sure how to approach the turn in this hand. I don't really like checking since I am out of position and if I check he will make a bet I have to call. I don't have strong reads on the player except he seem to be a little passive as is the whole table. I couldn't find a fold when raised due to pot odds. Is this a place I should be finding a fold?
